No problem,always try to be a strong,these symptoms due to the performance at peak.Try to avoid call girls and masturbating also consult with doctor and back towards real life enjoyment with wife.
The fact that you can get an erection with your gf proves that there cant be too much wrong. Some people say that if you dont want to be doing something, emotionally, then you can physchiologically stop yourself doing it.. So in this case if you dont want to be masterbating to porn or be with call girls then your brain may be sending those signals to the rest of your body.
I hope the call girls are in your past though and that your wedding goes well.
